MoTeC Outputs 7
Outputs
Both the E888 and E816 include 8 Auxiliary Outputs that are individually
controllable for frequency and duty cycle. They are known as PWM – Pulse
Width Modulated – outputs.
The outputs are in two groups (odd and even) with different characteristics as
follows:
Duty cycle for PWM1/3/5/7 is adjustable from 0 to 100% in 255 steps.
Frequency for PWM1/3/5/7is adjustable from 8Hz to 5kHz.
Duty cycle for PWM2/4/6/8 is adjustable from 0 to 100% in 20 steps.
Frequency for PWM2/4/6/8 is adjustable from 1Hz to 100Hz.
The PWM outputs each have high and low side drivers. A duty cycle sent to the
E888 is the low duty cycle ie:
• an output with 100% duty cycle is pulled low
• an output with 0% duty cycle is pulled high
If the frequency for an output is set to 0, then the output is turned on/off
according to the following rules:
• For a duty cycle of 0%, the output is off (ie: pulled high)
• For a duty cycle greater than 0%, the output is on (ie: pulled low)
All outputs are disabled until the first CAN message is received.
Outputs are disabled after no CAN messages have been received for one
second.
Output Configuration
Auxiliary Devices connected to the E8xx outputs can be configured in the same
way as those connected directly to the ADL. This requires that the ADL is
upgraded to version 3.1 or later.
In Dash Manager go to ‘Inputs – Communications’ and select an empty CAN
tab. Click on ‘Select’ and choose ‘Expander Outputs’ from the list.
